Section 9. Calibration and Zeroing
Now you can view the current reading on the sensor to be calibrated. Set the
sensor to the known value (“calibrate to” value). Enter that value into the
Enter Calibrated Value box. Press Calibrate. The current value will show
Calibrating until the process is complete. You will then have the opportunity
to press Finish, or press Previous to return and calibrate more sensors.
9.7 Strain and Shunt Calibration
In addition to the FieldCal instruction that performs calibrations on
measurements, there is a specialized instruction for performing calibrations on
strain bridge measurements (strain or shunt calibration). This instruction is
called FieldCalStrain. It functions in a similar manner to the FieldCal
instruction, but has additional arguments to meet the specialized needs for
shunt and strain gauge calibrations. It uses the same calibration file (*.cal) as
well as the other utility calibration instructions (SampleFieldCal, NewFieldCal,
LoadFieldCal). For more information about how to use these instructions,
refer to the FieldCalStrain instruction section of your datalogger manual, or
refer to the online help topic for FieldCalStrain within the CRBasic Editor.
The Program Generator can generate programs using this functionality for the
¼ Bridge Strain, ½ Bridge Strain and Full Bridge Strain measurements. Short
Cut can also generate programs for the ¼ Bridge Strain measurement. The
Calibration Wizard also assists users through the process of calibrating sensors
in a program using the FieldCalStrain instruction. For more information, refer
to the online Help topic provided within the Wizard.
